In this paper, we have made an analysis of the needs for a multiple interface in designing agent-based participatory simulations that can be integrated in a collaborative platform.
Our current solution only provides a personalized view and control of parameters and outputs. Thanks to this customization, the stakeholders can easily participate in the simulation from their offices and collaborate in a distributed simulation with a personalized interface according to their specific role.

In the concept part of our work, we designed a generic model to add the agent-based participatory simulation into the collaborative frameworks for agent-based modeling and simulation. This work consists of the representation of the modular structure for a web collaborative portal for generic participatory simulation tools on the previous version \cite{PAMS:2008} that is a strategy to improve flexibly a unique interface to multiple interface in using a DTD structure to define the necessary components of a generic constraints for the rights of the roles of the XML configuration file. The XML file that is validated by the DTD structure will describe specifically the roles, the elements of a role by determining the views and controls of a role in a model for participatory simulation.

In the practical step, we apply this concept to adapt the current version of PAMS, a collaborative simulation platform. The extension of our work serves new collaborative strategy in the experimental process with a specialized interface for each participant. It allows us to explore and examine more effectively amongst participants and experts who come from many different disciplines.

In this improvement, the interface that we created can easily assign the personal interface for modelers to test the reactions of the user. Experiments of participant behaviors allow us to compare the conditions of action of the current model and in reality. Our work in this situation still has been yet completed: such as the ability to control and manage the actions of the agent or the lack of a decision assistant. In the future work, we will continue on this concept to build a group-ware for participatory simulation more perfect.
